This jumper controls the Firmware Hub (FWH) locking function. When set to LOCK, it prevents
programming or block erase to the top block of FWH. There are 8 blocks of addressable
space controlled by the FWH. The top block (block 7, also called Boot Block) stores some
critical codes. To guard against accidents (such as a virus, program bug etc.), we recommend
that you lock this block. Even if other blocks were to be erased, you could still recover your
system easily by following the 2 steps below:
1. Reboot with DOS (95/98) system boot floppy disk.
2. Reflash BIOS according to section 5.3, Step 5 (Page 61).
